PCIe EM Service Overview

A pair of PCIe EMs is assigned to each server module in the chassis.
All PCIe EMs connect to a chassis midplane. The midplane provides an interconnect
between the server modules and the PCIe EMs installed in the chassis. The
midplane connections between the server module and the PCI EM are logically defined by
the midplane.

If the amber Service Action Required indicator on a PCIe EM is lit,
this indicates a problem with the PCIe EM.
